Biological activity and chemical characteristics of dredge material from ten sites on the Upper Mississippi River:
Sampling Purpose: In 1980, the U.S. Fish and Wildlife Service, National Fishery Research Laboratory, conducted a study to determine the biological activity and chemical characteristics of dredge material from 10 sites on the Upper Mississippi River between St. Paul and Winona, Minnesota (Pools 2, 3, 4, 5, 5A, and 6). Composite grab samples were analyzed for volatile matter content, particle size, metals, organochlorines, polychlorinated biphenyls, and petroleum-related compounds. The toxic effects of the sediments were also assessed in static bioassays with a variety of aquatic organisms. Sample coordinates were not provided with this study; however, coordinates were approximated in ArcView using detailed site descriptions.
